Why Tesla Optimus’s Dexterous Hand Remains a Core Engineering Challenge

AI summary

TMTPost reports that, during Tesla’s Q3 2026 earnings call, the Optimus engineering lead identified the dexterous hand as one of the hardware system’s most challenging components. Elon Musk said its fingers must be soft enough to handle delicate objects, durable enough to withstand repeated wear, and compatible with internal sensors. TMTPost’s analysis examines the related tradeoffs in grasping, handoff, force control, tactile sensing, transmission, maintenance, and long-term task performance.

In-depth insight

The remarks identify a concrete bottleneck in Optimus hardware: achieving reliable manipulation without sacrificing sensitivity, durability, or precise control.

我们最早从影视作品里认识的机器人,大多能徒手格斗、操作武器,甚至驾驶飞船。现实中的人形机器人离变形金刚、高达们的能力还有极为遥远的距离。但拿起桌上的杯子,把一副眼镜递给身边的人,总该容易一些吧?

未必,做好这些小事儿对我们人类来说很轻松,对机器人来说可就太难了。

当地时间10月21日,在特斯拉2026年第三季度财报电话会上,Optimus工程负责人仍将灵巧手列为最具挑战的硬件部位之一。马斯克谈到了其中的矛盾:手指要足够柔软,能够拿起易损物品,又要经得起反复使用的磨损,里面的传感器也不能因此受损。

2007年的《变形金刚》里,擎天柱能接住从高处坠落的山姆,也能从地面拾起他那副细小的眼镜。接人有多难,我们大致能想象;捡眼镜却很容易被一带而过。那几根巨大的金属手指,怎样才能伸到镜腿下面,拿稳它,又不把它捏坏?从拾起到递出,这一连串动作能检验灵巧手的抓握与交接能力;用久之后再做一次,还能看出参数表没有说明的问题。
